(crise-34) 3 Claims.

in the art of hair waving andA more particularly to the novel construction of a rod upon which the hair is wound or wrapped to impart permanent curls thereto.

Various processes for imparting a permanent wave to the hair have been practiced for many years, butl these processes have depended primarily upon the `application of electrically developed heat and required a time c ycle measured in hours. The newer hair waving methods have been developed to eliminate the necessity of the customer spending uncomfortable hours under the electric heater.

One of the more promising of the newer processes is known as the cold wave process. In this process the head of hair is sectioned off and each section is wound or lwrapped around a small diameter rod to form curls. The number of rods required depends upon the ease or difliculty with which the particular hair curls are formed, but ingeneral` 'approximately thirty rods are required to wave the average head. The curling rods are provided with a metal spring, or elastic band whichcan be snapped overthe curled hair to maintainz the hair in thecurled state and to retain the rods in suspended position about the scalp. After 'A all the hair is curled around the rods, the operator applies a preferred chemical solution to all the individual curls either directly from a bottle, from a bulb syringe-like injector, or by means of a small brush, cotton dab, etc. The entire head is then enclosed within a suitable cap for approximately thirty minutes during which time the chemical solution reacts with the hair to impart a permanent Wave thereto.

The cold wave process has not met with universal acceptance and I have found that the main reason for a large percentage of failures is the inability of an average operator to properly wet the individual hair strands with the chemical solution. I have found that to produce acceptable results all hair strands must be completely and uniformly moistened by the solution, but there exists at present no certain way of accomplishing this. Inasmuch as each curling rod contains a bundle of hair curled into a mass several inches long and approximately an inch in diameter, it is apparent that the normal methods of moistening the mass externally do not permit penetration of the solution to the inner layer of hair strands. Consequently, the inner hair curls do not receive a permanent set and as these inner curls are the extremities of the hair the completed job ls not at all pleasing 2 to the customer.` Experienced operators have developed personal knacks which make it possible to produce a practical percentage of acceptable waves, but the average operator soon becomes discouraged and reverts to the old heat process.

A curling rod made in accordance with my invention makes it possible for inexperienced operators to completely and properly moisten all the hair of the curl .and thus assure good results.

An object of this vinvention is the provision of a hair curling rod which is adapted for use with a small hand syringe whereby the hair waving solution is applied to the hair under pressure thereby vassuring even ldistribution of the solution.

Another object of this invention is the provision of a hair curling rod having an axial bore in one end thereof and connecting with longitudinal slits in the body of therod whereby liquid forced into the bore will seep `out through the slits substantiallyalongI the entire length of the rod.

Still another object of this invention is the provision of a hair curling rod provided with a relatively heavy washer rotatably secured near one `end thereof and a iiexible rubber strap looped through the rubber washer in such manner that the strap may be stretched across a band of hair curled round said rod to retain the hair and rod in fixed position on the head.

v These and other objects and advantages will be apparent vfrom the following description when taken with the accompanying drawing which illustrates one embodiment of the invention. The drawing is for purposes of illustration and is not to be construed as defining the scopes or limits of the invention; reference being had for this purpose to the appended claims.

In the drawings that follow, like characters identify like parts in the various views:

Fig. l is an isometric View of a rod melde in accordance with my invention;

Fig. 2 is a central longitudinal sectional view of the rod shown in Fig. 1;

Fig. 3 is an isometric view of the rubber washer;

Fig. 4 is an isometric View of the rubber strap;

Fig. 5 is a front View of the rod showing the rubber washer and strap assembled thereon; and

Fig. 6 is a view of the complete rod showing the hair curled thereon, the strap in its hair retaining position and the manner of injecting liquid into the rod by means of a hand syringe.

Referring now to Fig. 1 and Fig. 2, the numeral Ill identifies a rod of generally concave form, that is, having a progressively increasing, circular slit as described is suflcient for practical :puma

poses but it is obvious that a plurality of slits may be employed.

Fig. 3 illustrates a relatively thick rubber washer I5 having a hole l'fthatzis offra :diameter somewhat larger than the diameter awfrthe rod IU at the bottom of the circumferential groove I2. Thus, the washer I5 may be forcedl over-.the rod to loosely occupy the groove I2 as shown kin Fig. .5; the rod .and Washer being ,readily .rotat'able one rerativetotne father. 'The washer f5 als'o includes 'aninteg'ial extension I1 having an opening '1'3 cut or jpunc'he thereinior purpcses .described "below,

'A p'i'iablerubber 'strap "V9 'f-the 'general'form shown in Fig. 4 includes .a hole .20 at one 'en'd and `aiuole/2l at the other jenel.

LBy assembling the strap 'and v'vvasher inlzhis manner, the strap has anormal tendeneyito'extend 'to-the righil as s'hivii aiii'na'gy, therefore,"be 'convenientlyheld by the 'operator "in the palm ofthe right nana.

The solution rapidly emerges from the slit I3 and being subjected to material pressure, the liquid oozes throughout the entire mass of hair. thus completely moistening all individual hairs evenly and thoroughly.

Having now kdescribed my invention fvarious charrges'may be made in the construction of the parts without departing from the scope and spirit 'of the invention as set forth in the claims.
